HOSE- COUPLING.

Specification of Letters Patent Pai entail Fll. l5, 19() Application inea september 9, 190s. serial No. 452,342.

To all mlm-m it may concern:

llo it known that l, ll'nmsii J. "VMT, :i subject ot' the. King of Great Britain. and n resident of lloodstock. in the county of Oxford. in the lrovince of Ontario, Canada, have invented a new and useful Hose-Coupling7 ot which the following is a specification.

Ilhis invention relates to u device for temporarily joining sections of hose end to enel.

'lhe ohject of this invention is to provide :s pnir of interlocking connecting pieces hy means of which the ends ol hose sections nre readily and easily joined together in line, and so constructed thatall possibility of leakage is avoided and completely prevented, greater pressure will therefore he innintained where this hose coupling is employed.

A further object is to ennhle hose. sections to he g'oined together by one man. and more easily and rapidly than two men cnn couple the hose .sections together with the hose. couplings in ordinary useJ and a further ob ject is to provide a device that is siniple, strong and durnhle in construction and one that con he manufactured at a considerably less cost. than the hose couplings in ordinary Y use. And this invention consists of the iinproved construction and novel combination of parts of two interlocking connecting pieces, as will be hereinafter first fully set forth and described and then pointed out in the claim, reference being had to the accompanying drawings forming part of this specification, whereinzt Figures 1 and 2 are perspective views of the entering and receiving interlocking sections of my improved hose coupling. Fig. 3 if: :mother perspective view ot' same, showing` the interlocking sections coupld together. Fig. viis a central longitudinal sectional view of the interlocking sections of the/hose coupling, showing their position when coupled together.

Veither describing my invention with refcrcncc to tl-.c accompanying drawings, the numeral 1 designates the entering or male interlocking tnlliilnr scf-tion of my improved hose coupling, und. i.: provided with :m a l1 nnlur groove or recess and oppositely disposed trnnnions; n pomion of the outer face of said interlocking section 1 is formed nurrowcr in cross section at one end :is shown at, a, in Fig. 1, to form a shoulder, l), winch extends entirely nronnd snid section, l', and

extending from -::td shoulder. i. mor on said Aportion. a. is n register-ingr projection. 'cj

4 is the receiving! or l'eumlc interlockingr tuhulnrL section provided with .studs fr. il notch (l to rvcciw the projet-lion f und with internal curved shoulder T.

S is a packing ring' of ruhhcr or othcr cx; punsihle material which is ,sccurclv held in )lace on said interlocking scct'ionl hv hcing fitted to and inserted in thc groove 2 formed in sind interim-king .section l.

5l nre levers coupled together :d one end hy the yoke. J. :ind on the other end ot euch of Suid levers il hooks er. nre formed. und. j. is :i shallow recess forint-il in :inch ol' sziid hooks. e, of'said levers .l. The levers 9 are Vnivotzilly iuountml on the trnnnions Il with which the interlocking .section 1. of the hose coupling is provided.

10 is :i screw which isecured in n screw threaded socket in euch of Suid trunnions 3,

and 11`is a washer on euch of said screws l0 which nnsher is interposed hctn'ecn the end of the trnnnion 3 :ind the hond of the screw 10 to securely hold the levi-rs J on suid trnnnions I.

12 is n shallow recess formed in the outer face of the interlocking section 1 which recess is arranged to come :Inder the yoke, d, when the latter is closed on the section 1 as shown in Fig. 3, :md 13 is a short metallic har flattened at one end which ns shown in Fig. 3 is adapted to be inserted in the shullovv recess l2 henenth the yoke. (I, und bc- -twccn the latter und the interlocking section 1.

14 is an inner :square shoulder also formed on the inner face ot' the section 4.

The ends of the sections of the hose, 'not shown, may he inserted and secured in the ends, und, h, of the inlerloclrinlr sections 4 and 1 hy means of expansion col nrs, or in any manner or by any means found most suitable or convenient.

viren the ends of lengths ot fire or other hose are Secured in the ends of the interlocking sections l and i. the lutter :irc firmly und securely joined together as follows:

The reduced end ortion, a, at the. free end of the interlocking section, l, is fitted to and adapted to enter and slide freely into the free end of the interlocking section 4, until the shoulder. is only slightly separated from the adjacent end of the in terlocking section 4, when so adjust ed the end of the interlocking section 1 is only slightly separated from the shoulder 14- in the section t.

lVhen the end, a, of the section l opposite the end ofthe section, 4, is adjusted to bring the projection, c, oiythe section l in line `with the notch (E on the section -lthe studs. 5 will be in line with and in proper position to oe engaged with by the hooked ends, e, of the levers 9.

|vi'hen so adjusted the yoked levers 9 are in the position shown in Fig. l, when by pressing thc yoke, d, toward the. coupling until the said yoke abuts against. said coupling the hooked ends, c, of said levers S) will engage with the studs as shown in Fig. 3, and the coupling sections l and -l firmly and seeurel)v joined together.

lVlien adjusting the levers 9 from the position shown in Fig. 1, to the position shown in Fig. 3, just at the completion oi this operation, the shallow recesses. f, are so arranged to come opposite the studs 5 and. lthe latter snap or click into said-ieccsses, this locks and firmlyv secures said hooked ends,e,

ot said levers t) on said studs 5. so that aii er1- cess ot or incre than ordinary force irill have to be applied to said levers 9 in order t0 disengage them from said studs 5. As the hooked ends, c, of said levers 9 are adjusted 'from the position shown in Fig. l to the position shown in Fig. 3, the annular packing ring 8 of rubber or other expansible material in the annular groove or recess 2 is compressed tightly against. the interlocking section L and against the curved shoulder 'i' on the interior face of the interlocking section 4.

The interlocking sections l and d thereftnje, are not only firmly joined and locked together but the packing ring S arranged and secured in place as described avoids and completely prevents any possibility of leakage. j

As the only operation thatis iequired to join these iiilerlmking sections l and 4 t0- gether, is to slide one interlocking section into the other and press the yoke, d, against the coupling, the joining of a hose section or sections together may be more rapidly and easily accomplished by oneman where this coupling is employed, than can be accontplished by two nien with the hose couplings in ordinariv use.

To unlock the coiiplin "ections and 4 in order to sepai .ite them, allthat is necessary i to do is to insert the flattened end of thtj ll'itne har 13 in th. shallow recess 1Q under the yoke, d, and pry up the latter until the hooks,

l e, of thc levers 6 are disengaged from the studs 5, when the hose sections may he readilj7 and easily separated by withdrawing the section 1 from the section 4.-

When the interlockingsections l and are separated, the fact that the expansible paolo ing ring 8 is inserted in the groove Q, all possibility' of it becoming accidentally detaehed or lost is avoided. Again as the interlocking sections l and do not require jthe screw threads or rotating shouldered sleeves of the hose couplings in ordinariy use,

my liose coupling will cost very innch less t o manufacture, will consequently he very Asimple in enstruction, at the .saine time, strong and durable and etlicient in operation.

Having thus described my invention, claim'.

A nosecoupling comprising a male niember and a female ineniber, said male member havin(Y a. reduced entering end portion of two diameters whereby a pair o shoulders are provided on said reduced portion, that portion of smaller diameter provided at a point removed from the outer end thereof 4 with an annular seatof semi-circular shape l in cross-section, said seat terminating in a l shoulder formed by that portion of smaller l diameter, a projection carried by the shoulj der foi-ined hy that portion of larger diameiter and projecting upon said portion of \larger diameter, and trunnions carried by female inenihei', the other of said shoulders adapted to engage one o the. shoulders in said adapted t-o'engage thev inner end of the male l member, sinds carried on opposite sidfis of the female member and locking means for said members winpiisinf side arms pivotcd l on the triinnions ot' the niale member and *connected at one ena by a voire integral i therewith, thel other ends of said arins prol jectiiig beyond the truniiions and being hook j shaped to receive the studs on the female member. f l In testimony whereof, I have signd in jthe presence of the bvo undersigned w"- nesscs.
